The aim of this study is to evaluate the association of TGFA TaqI polymorphism with nonsyndromic cleft lip and/or palate (NSCLP) in an Iranian population.
In this case-control study, 113 children with NSCLP and 209 controls were included. Genotyping of the TaqI polymorphism was performed by polymerase chain reaction and restriction fragment length polymorphism methods. A p-value of <0.05 was considered statistically significant.
For the TGFA TaqI polymorphism, the distributions of genotypes in the NSCLP (p = 0.810) and control group (p = 0.422) were in Hardy-Weinberg equilibrium. There was no statistically significant difference in the genotype distribution (p = 0.059) and allele frequency (p = 0.065) of the TGFA TaqI polymorphism in the NSCLP and control groups.
TGFA TaqI polymorphism was not associated with the risk of NSCLP in Iranian children. Birth Defects Research 109:1386-1389, 2017.© 2017 Wiley Periodicals, Inc.
本研究旨在评估 TGFA TaqI 多态性与伊朗人群中非综合征性唇腭裂（NSCLP）的关联。
在这项病例对照研究中，纳入了 113 名 NSCLP 患儿和 209 名对照。通过聚合酶链反应和限制性片段长度多态性方法对 TaqI 多态性进行基因分型。p 值<0.05 被认为具有统计学意义。
对于 TGFA TaqI 多态性，NSCLP 组（p=0.810）和对照组（p=0.422）的基因型分布均处于哈迪-温伯格平衡状态。NSCLP 组和对照组的 TGFA TaqI 多态性基因型分布（p=0.059）和等位基因频率（p=0.065）无统计学差异。
在伊朗儿童中，TGFA TaqI 多态性与 NSCLP 的风险无关。出生缺陷研究 109:1386-1389, 2017.© 2017 Wiley Periodicals, Inc.
